[0027] The invention: the vertical line and the sand mold base use the same old sand, and the two sand mixers separately mix the sand for their own use. According to the various indicators of the old sand in the laboratory, when the sand for the vertical line is mixed, 0.5% of bentonite and coal are added. Powder 0.5%. The sand formwork only needs to be supplemented with 0.25% of bentonite. The added amount of bentonite is 0.75% less than the 1% supplementation ratio of the simple sand-milling formwork, and the amount of coal powder added is 0.6% more than that of the simple sand-milling formwork. The proportion will not be added directly. For example, when the mud content of the sand mold base is lower than the warning line of 12-13.5, the dust removal ash can be added during the mixing and grinding. When the sand is mixed, the sand in the feeding box 5 is continuously reduced At this time, the slider 10 drives the T-bar 11 to move through the elastic force of the second spring, and the T-bar 11 moves to drive the feed box 5 to move. At the same time, the feed box 5 moves to drive one horizontal plate 5 to move closer to the other horizontal plate 15.
